Teams share slides are delayed to the participants

Gents, 

Recently we are facing a huge latency on Teams while sharing presentations via share screen means while the presenter in slide #8, some participants in slide 2 or 4 ( lagging), we checked the call health we find some packet loss may reach 10 - 20%.

network team checked the internal network and they find nothing in all layers!

we opened a couple of tickets with MS team support without more help to identify the root cause of the issue or find the solution.

any experiences with the same ?

thanks for understanding and supporting!

regards
